It caused the serious contamination of local region and trace contamination\\nthroughout adjacent towns and prefectures. The subsequent transfer of radionuclides,mainly radioisotopes such as T and caused radiation exposures after the accident. In order to investigate the effect of the accident of the nuclear power plant on environment, I employed the measuring method of tritium applying a distillation process and an electrolytic enrichment process. The specific activity of tritium(T concentration) in the water thus obtained was measured by liquid scintillation counter.\\nThis procedure was applied to monthly and short term precipitation in Ｎiigata city, spring water in both Fukushima and the adjacent prefecture, and to lake water in both Fukushima prefecture and Niigata city.Furthermore, I also measured the\\nconcentration of ions (Na＾+,K＾+, Ca＾\u003c2+\u003e,Mg＾\u003c2+\u003e,NH_4＾+, SO_4＾\u003c2-\u003e,NO_3＾-, and Cl＾-) in precipitation, spring water and lake water.From the above-mentioned, the following matters have been obtained:", "subitem_description_type": "Abstract"}, {"subitem_description": "(1) The variation of T concentration in recent years can be clarifIed.
